因为键盘弹起，导致调出的扫码界面黑屏。

[SunLongbri]

当在TextField组件的suffixIcon设置点击事件时，因为键盘谈起的原因，导致调出的扫码界面黑屏。

代码：此处为TextField中的代码，其他没有键盘弹起的地方调用扫码界面，完全正常。

      suffixIcon: InkWell(
        splashColor: Colors.transparent,
        highlightColor: Colors.transparent,
        onTap: () {
          JumpReceive()
              .jump(context, Routes.deliveryOrderScanQrPage)
              .then((value) {
            print('扫码结果》》》》' + value);
            setState(() {
              _codeController.text = value;
            });
          });
        },
        child: Container(
          padding: EdgeInsets.only(
              top: AutoLayout.instance.pxToDp(12),
              bottom: AutoLayout.instance.pxToDp(12)),
          width: ScreenUtil().setWidth(36),
          child: Image.asset('images/search_scan_icon.png'),
        ),
      ),

结果：
